Restenosis after coronary angioplasty: A multilvariate statistical model to relate lesion and procedure variables to restenosis [PDF]

, 1991
The Multi-Hospital Eastern Atlantic Restenosis Trial group obtained follow-up angiography in 510 patients with 598 successfully dilated coronary lesions who were enrolled in a controlled trial of the effects of a single dose of 1 g of methylprednisolone ...

Spatial Mismatch Between Angiographic Obstruction and Plaque Destabilization in Acute Coronary Syndromes: A Conceptual Narrative Review

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT The identification of the “culprit lesion” in acute coronary syndromes (ACS) traditionally relies on coronary angiography, assuming that the most severe stenosis, abrupt occlusion, or largest filling defect marks the site of plaque destabilization.

Late Restenosis Following Sirolimus-Eluting Stent Implantation [PDF]

, 2011
ObjectivesThis serial angiographic study evaluated the incidence and predictors of late restenosis after sirolimus-eluting stent (SES) implantation.BackgroundPrevious studies showed late restenosis (i.e., late catch-up phenomenon) after implantation of 7-

Mechanisms and Management of Acquired Aseptic Intracardiac Communications After Transcatheter Aortic Valve Implantation: Single‐Center Case Series Insights

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Acquired aseptic intracardiac communications (AICCs) are rare but clinically relevant structural complications following transcatheter aortic valve implantation (TAVI), typically resulting from mechanical injury to the aortic annulus, interventricular septum, or adjacent structures.

Balloon‐Stopper Retrieval and Peripheral Parking After Inadvertent Ostial Right Coronary Stent Deployment

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Percutaneous treatment of right coronary artery (RCA) ostial lesions is technically challenging due to cardiorespiratory motion. Case Summary We describe a 70‐year‐old man undergoing PCI for an ostial RCA lesion where a forceful cough caused complete stent expansion within the aortic root.

Use of Nuclear Magnetic Resonance Imaging Angiography to Follow-Up Arterial Remodeling in an Animal Model [PDF]

, 1998
Appropriately sized arteries in small animals may be possible models for studying the remodeling process as occurs after arterial balloon injury in humans. Magnetic resonance imaging (MRI) is able to noninvasively image tissue in vivo.

Engineering an artificial trachea: Quantitative benchmarks and modular strategies for mechanics, epithelialization, and vascular integration

FlexMat, EarlyView.
In this work, we first examine the limitations of surgical repair and stenting, including migration, granulation, mucus plugging, and infection. We then translate these failures into engineering constraints involving geometry, mechanics, fixation, degradation, junctional stress, and remodeling.

Balloon angioplasty for the treatment of coronary in-stent restenosis: immediate results and 6-month angiographic recurrent restenosis rate [PDF]

, 1998
Objectives. The purpose of this prospective study was to evaluate the immediate results and the 6-month angiographic recurrent restenosis rate after balloon angioplasty for in-stent restenosis.Background. Despite excellent immediate and mid-term results,
